我有一个带有Spring集成的Spring boot项目。据我所知，它使用分散-聚集模式：

@Bean
public IntegrationFlow getClientsFlow() {
    return IntegrationFlows.from(FIND_CLIENTS_INPUT_CHANNEL_NAME)
            .transform(inputMessageConfigurer())
            .scatterGather(
                scatterer -> scatterer.applySequence(true)
                    .recipient(ONE_FLOW_CHANNEL_NAME)
                    .recipient(TWO_FLOW_CHANNEL_NAME),
                gatherer -> gatherer
                    .releaseStrategy(
                            new MessageCountReleaseStrategy(2))
                    .messageStore(new SimpleMessageStore()).outputProcessor(messageGroup -> {
                        List<TWOClient> twoClients = getMessagePayloadWithType(messageGroup,
                                TWO_MESSAGE_TYPE);
                        List<ONEClientAccount> oneClientAccounts = getMessagePayloadWithType(
                                messageGroup, ONE_MESSAGE_TYPE);
                        ClientAggregator aggregator = new ClientAggregator(twoClients,
                                oneClientAccounts);
                        return MessageBuilder.withPayload(aggregator.aggregateClients())
                                .copyHeaders(messageGroup.getOne().getHeaders()).build();
                    }))
            .get();
}

它工作正常，但有时日志中会出现错误：

这是来自
HeaderChannel注册表的UUID
：

if（消息通道的通道实例）{
字符串名称=this.uuid+id.incrementAndGet（）

您的配置中似乎有一些标头enricher，其功能如下：


/**
 * Add header specifications to automatically convert header channels (reply, error
 * channels) to Strings and store them in a header channel registry. Allows
 * persistence and serialization of messages without losing these important framework
 * headers.
 * @param timeToLiveExpression the minimum time that the mapping will remain in the registry.
 * @return the header enricher spec.
 * @see org.springframework.integration.support.channel.HeaderChannelRegistry
 */
public HeaderEnricherSpec headerChannelsToString(String timeToLiveExpression) {


因此，您是对的：对于
replyChannel
头，从注册表中删除这些条目需要一个超时，这对于您的逻辑来说是不够的

尽管不清楚您是否仍然需要
headerChannelsToString（）
选项
